USDA's Joint Ag Weather Facility says on the Plains, wheat continues to enter its period of winter dormancy under a cold, mostly dry weather regime. "A patchy, generally shallow snow cover is insulating a portion of the wheat crop," USDA adds.
In the West, freeze warnings have been lifted across California's San Joaquin Valley, although some frost has occurred for the fourth consecutive morning, according to USDA. "Elsewhere, dry weather favors late-autumn fieldwork, including Arizona's cotton harvest, which was 70% complete by Dec. 4," USDA reports.
In the Corn Belt, USDA says late-season fieldwork remains largely on hold in Ohio and neighboring states, despite a return to dry weather. "By Dec. 4, one-fifth (20%) of the Ohio corn crop remained in the field," USDA adds.
In the South, USDA says freeze warnings are in effect this morning as far south as south-central Texas and much of Louisiana. "However, the winter agricultural region of Deep South Texas was spared a freeze, while temperatures were not low enough to pose a significant threat to sugarcane in Louisiana," USDA explains. By Dec. 4, only 16% of Louisiana's sugarcane remained in the field, well below the five-year average of 31%, USDA says.
USDA's outlook says during the next five days, generally cool but tranquil weather will dominate the U.S. "Significant precipitation will be confined to southern Texas, where weekend rainfall may exceed an inch," USDA says. Showers may develop along the southern Atlantic Coast, while some light snow may fall across the Midwest and Northeast, according to USDA. "By early next week, rain and snow showers will overspread the Southwest," USDA says. During the weekend, USDA says temperatures will rebound to above-normal levels across the northern Plains—and that bubble of mild air will spread eastward by early next week.
